one author (Kique/Johaan Nordic, author of Home/Asmundr on Smackjeeves) have been doing something quite cool and funny (and informative) for almost each of his anniversaries:
make a tally of different things that happened in the story, and present them in a funny or meme-like manner
such as: number of times [character name] cursed, number of times characters broke in tears, number of times the jokes flew over [name]'s head. number of times [name] lied. number of times [name] won/lost a fight, ...etc.
and then added a section of little hidden details or easter eggs that we may have potentially missed.
then some "bloopers". reuse some panels and edit the text to make something silly out of it.
and then a little thank you at the end : >
happy anniversary in advance!
